Part of inner wheelhouse painted with Hammerite

Hi all, part of my inner wheel house has been painted with Hammerite (regular, not car-specific).

Before painting, I'm told the car had very, very mild first stages of rust. The car took a hit to its quarter panel. It's a rather recent car (2021).

Would you keep it, or try to scrub it off and cover with epoxy primer + waxoyl or similiar? (I have a shop that can try to get it off chemically, but if not, they'll go the mechanical route)
